U.AA(ESO)Abstract:TIMMI, ESO's 10 j.Lm instrument (for a detailed description of TIMMI see e.g. Kaufl et al. 1992, 1994) was mounted at ESO's 3.6-m telescope from July 15 to July 31 to provide for infrared imaging with broad- and narrow-band filters in the 5 and 10 j.Lm atmospheric windows. The purpose of the observations was twofold: • to investigate and monitor the atmospheric consequences of the impacts (P.1. Tim Livengood, NASA GSFC, Greenbelt, Md) • to search for global oscillations of Jupiter resulting from the impacts (P.1. Benoit Mosser, lAP, Paris) The observing time was shared between the two programmes and the filters were chosen strategically in such a way that the data are in principle useful for both programmes.References:H.U.
